TYPE-CASTING MOLD.

Application filed September 1, 1922.

To all whom it may concern 7 Be it known that I, GEORGE G. DrvnY, a subject of the King of Greece, residing at New York, in the county of New York and State of New York, have invented new and useful "Improvements in Type-Casting Molds, of which the following is a specificat1on.

This invention relates to slug casting molds for use in connection with type casting machines and the invention is particularly directed to means for casting what I will refer to as low ribless slugs.

In slug casting machines, it is a well known custom to cast ribbed slugs which when out are thicker at the top than at the bottom, and their evenness secured by afterwards trimming the ribs, cutting the same away more at their top portions than along their lower portions. In the case of ribbed slugs when it is desired to use same next to loose type, around boxes or as column rules, it is impossible to provide same with smooth surfaces against the material they come in contact with. 7 It is an object of my invention to provide an attachment for use in connection with the present well known molds wherein the usual form of mold cap and liners may be em ployed without loss of time or requirement of changes or other adjustments and associated with my attachment to form a low ribless slug which will be of uniform thickness throughout.

A still further object of my invention is to provide means for casting a ribless low slug of even thickness which will not work up in printing as is the case with high slugs and one which can be cut into labor saving sizes and used in composition next to loose type, or as quads, etc., while being generally useful as a spacing material for all purposes.

A still further object of my invention is to provide an attachment of the character specified wherein no time is lost in applying same to an ordinary mold.

A still further object of my invention is to provide an attachment for ordinary forms of molds wherein an even ribless slug is formed and provided with a straight face and base, the attachment being constructed whereby the molded slug is held against being drawn backwards by the retreating mouthpiece after the casting operation and thereby held against being overtrimmed by theback knife, which further prevents the Serial No. 585,696.-

slug from being trimmed less than the desired height. 4 i

With the above and other objects in View which will appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangements of parts which will hereinafter be fully described and particularly pointed out in the claims.

In the accompanying drawings, has been illustrated, a single and preferred form of the invention,'it being, however, understood that no limitations are necessarily madeto the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claims may be resorted to when desired.

Figure 1, is a perspective view of a mold showing its parts separated and looking toward the under face of the mold cap, my improved attachment being illustrated between the cap and base of the mold.

Figure 2, is a transverse section through the mold when locked showing my attachment operatively arranged between the sections of the mold for casting a low-ribless slug.

Figure 3, is a perspective view of a cast slug. t

Figure 4, is a transverse section through the slug, and

Figure 5, is a plan view of a modified form of plate for casting a high slug. 7

In carrying the invention into practice, use is made of a well known mold 10 which includes a lower section 11 and a cap section 11 the former provided with slightly tapered liners 12-12 and vertical end pins l313. These pins 1 313 are extended through the slots 1414 in the ends of the cap section 11, so that the cap section of the mold can firmly and uniformly clamp against the base section 11 when the mold is set up ready for the casting operation. The mold cap 11, is provided upon its under surf-ace with grooves 15, which when the 'li'ners 1212 and the cap section 11*, and

provided on its under side near one of its longitudinal ed eswith a depending ridge 17 whidhjenten sjinlto the mold-cavity and as shown, the ends ofthis ridge rest directly upon the liners 1212. This plate serves to close against the grooved face of the cap section 11, of the mold and as illustrated, the ends of the plate are notched at 1 8-18 to accommodate the pins 1 31 3 and to coact therewith so that the plate is uniformly peei i d be wee t s t on w t th edge lll'thereof flush with the inner surface of themold." The opposite edge ofthe plate ,is slotted longitudinally between its endsat 19,", so that thisedge com'es slightly inwardof the outer surface of the mold. When deplete 16 isamn ea in the mold as described 'the ridge'l'f servestlirough the fact that it rests upon thereduced ends of the aforesaid liners ,12 12 to space the plate from the ripper surface of the section 11 so thatjtliemoldfcavit will be ofa uniform depth throughout. lhe mold cavity is thus partly defined by the up i r surface of the section 11 of the mold a theunder surface of the plate "1:6 between the liners 1212.

e rear side of the mold cavity is adapted to receive the en-en netalin the usual man 7 surface 20, of said member. v

course be understood that the member 20 15.

In order to close the oppositeside of the mold, I employ a slide member 20 ,formed of brass and provided with a ridgefzl, adapted to enter. the "mold cavity between theends the sl0t 19. The surface of this ridge is beveled downwardly and inw'andly at 20, towardtlie cavity of the mold so'that it will freely engage with the mold cap 1 1. The member is provided with spring portions 22'22 adapted to permit the member to yield slightly when th Leap of the inold is brought against the beveled carried by the usualinatrix block 23, and the prin ti s 22 22 e re t with e Well 949i a cove tailslot 25 ft'ormed thematrix block to removably secure the slide member thereto.

On reference to Figure 2, of the drawing, it will be observed that the grooves 15 a in the cap section 11-", are graduallyof an increasing depth from one end toward the other end thereof and when the mold is used without my invention, the cast slug willbe provided with tapered ribs. Incidentto the provision of these ribs, the, slug isof a greater thicknesstoivard oiie side. i

7 With my invention, I am able to em loy the present form of mold-and cast there rom slugs of eventhicknessli No trin i ningfior cutting down of the slug sections are" required. V a

In Figure 5, I show a plate 21, ofun iform. width except at its ends. The said ends are notched at 22fto accommodate the afore-v said pins l3el3. Thefwidtli of this plate old. of the typ mp is co-extensive with the width of the mold cavity. The lat'eis otherwise tliesame as plate 16 and" y means thereof a high slug of uniform thickness may be cast.

From the construction ofthe member 20,

the ridge 21 normally clears the upper sur-' face of the' section 11 of the mold and when the mold advances (luring the casting operation, the base of the ridge 21 isbrought to bear against said upper surface of the section 11 through engagement otthetapered surface '20", with the mold cap. 11'. In this manner, Iain able to prjodncei'a low slug \Vhat I claim is I I 7 l.
